Fitbit Charge 2

A smartwatch that takes up very little real estate on your wrist, the new Fitbit Charge 2 automatically tracks runs, elliptical sessions and circuit training, offers guided breathing sessions for recovery and shows calls, texts and calendar alerts. The lavender/rose gold combo was a standout. ($180 for the styles shown here, available September 2016)

Fitbit Flex 2

A skinnier, virtually weightless version of the ubiquitous Fitbit Flex, the Flex 2 (seen here in lavender) has new features that includes swim tracking, light/vibration patterns when you're receiving a call or text, reminders to move and auto-activity tracking. ($100, available September 2016; for more on the bracelet see next slide)

Fitbit Jewelry

The new Flex 2 also fits in these chic bracelets and lariats, designed by Fitbit. The bangles will be $90 in silver and $100 in gold or rose gold; the necklaces will be $80 in silver and $100 in gold when the Flex 2 launches in October.

Public School Bands

Public School also created these limited-edition bands for the Alta—on the left is one inspired by a traditional chain-link watch and on the right, a hand-woven band. These will only be available in limited quantities later this fall.

Kate Spade

The always-adorable brand is launching predictably-adorable activity trackers of their very own, which will count steps, sleep, control your phone's music and even help you take a selfie. ($150, available November 2016)
